Cooling and heating blower

ABSTRACT

A cooling and heating blower has a base, a meshed case, a motor assembly, a fan and a cover. The meshed case is mounted on the base and has a top opening. The motor assembly is mounted on the base and extends into the meshed case. The fan is mounted on and rotated by the motor assembly, is mounted in the meshed case and blows air to the top opening. The cover is mounted on the top opening of the meshed case and has a bottom bowl and a heat source. The bottom cover is shaped to reflect air blowing from the fan to all directions. The heat source is mounted on the bottom bowl to heat the forced air.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention is a blower, especially a blower that can providecool or heated air in all directions.

2. Description of the Prior Arts

The purpose of a blower is to make a local environment more comfortableby providing forced cool or heated air. A conventional blower has a fanto force out air and may have a heat source to heat air. With referenceto FIG. 5, one kind of conventional blower is a stationary blower (60).With reference to FIG. 6, another kind of conventional blower is apivotable blower (70) that has a reciprocating direction swing. However,both kinds of the conventional blowers (60, 70) can only force air in alimited arc of travel at best. Although the head of the pivotable blower(70) can pivot to force air to several directions, the pivotable blower(70) still cannot blow air to directions such as the back of its head.As well, the pivotable blower (70) can only blow air to a singledirection at a time.

The invention is able to overcome the barriers of the stationary andpivotable conventional blowers by providing cool or heated air to alldirections to mitigate or obviate the problems.

SUMMARY OF THE INVENTION

The main objective of the present invention is to provide a cooling andheating blower that can blow air in all directions. The cooling andheating blower has a base, a meshed case, a motor assembly, a fan and acover. The meshed case is mounted on the base and has a top opening. Themotor assembly is mounted on the base and extends into the meshed case.The fan is located on and rotated by the motor assembly, which ismounted in the meshed case. The fan blows air to the top opening. Thecover is mounted on the top opening of the meshed case and has a bottombowl and a heat source. The bottom bowl is shaped to disperse the forcedair from the fan to all directions. The heat source is mounted on thebottom bowl to heat the forced air.

Other objectives, advantages and novel features of the invention willbecome more apparent from the following detailed description when takenin conjunction with the accompanied drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

With reference to FIG. 1, a cooling and heating blower in accordancewith the present invention comprises a base (10), a meshed case (20), amotor assembly (30), a fan (40) and a cover (50).

The base (10) has multiple switches (11) and a power supply means. Theswitches (11) are formed on the base (10). The power supply means ismounted on the base (10) and electrically connects to the switches. (11)Batteries or a plug (12) may be used to generate power.

With further reference to FIG. 2, the meshed case (20) is hollow, ismounted on the base (10) and has a top opening, a bottom opening, anannular top edge and multiple optional fastening holes (21) formedthrough the annular top edge.

The motor assembly (30) is mounted in the base (10), extends into thebottom opening of the meshed case (20) and is electrically connects tothe switches (11). The switches (11) control the transmission of themotor assembly (30).

The fan (40) is mounted on the motor assembly (30) in the meshed case(20) and is rotated by the motor assembly (30) to blow air to the topopening of the meshed case (20).

With further reference to FIGS. 3 and 4, the cover (50) may be hollow,is mounted on the top opening of the meshed case (20) and has an edge, atop bowl (51), a bottom bowl (52), a heat source (53), multiple optionalcase fasteners (54), multiple optional heat source fasteners (55) and anoptional head (56). The bottom bowl (52) is attached to the top bowl(51). The heat source (53) is attached to the bottom bowl (52) andelectrically connects to the switches (11). The switches (11) turn theheat source on or off (53) to start heating or stop heating air. Thecase fasteners (54) are attached to the edge of the cover (50) andextend through the fastening holes (21) in the meshed case (20) to mountthe cover (50) on the top opening of the meshed case (20). The heatsource fasteners (55) extend through the heat source (53) and the bottombowl (52) to mount the heat source (53) located on the bottom bowl (52).The head (56) is formed on the top bowl (51).

The advantage of the present invention is to provide a blower that candisperse air in all directions at a time. When the fan (40) rotates, theair blown by the fan (40) is reflected by the bottom bowl (52) thatcauses the air to exit the meshed case (20) in all directions.

Numerous characteristics and advantages of the present invention havebeen set forth in the foregoing description, along with details of thestructure and features of the invention to assist in the explanations.However, please note that the disclosure is illustrative only and is notfixed.
